The diet of Canis lupus in Latvia was studied from December 2001 to April 2008 based on analyses of 165 stomachs. Wild ungulates (cervids and wild boar) were the main food of the wolves. Cervids were found in 64.7% of the samples (69.7% of the biomass), wild boar in 25.9% of the samples (22.6% of the biomass), and beavers in 8.6% of the samples (6.4% of the biomass). The average mass of stomach contents was 824.1 g. Empty stomachs made up 26.7% of all stomachs. Statistically significant differences were found comparing variances of stomach content biomass between 1–2-year-old and adult animals and also in beaver remains in the diet of male and female wolves (12.9% and 3.2% of the stomach content biomass, respectively). There were no other significant differences in the diet composition, stomach content biomass, and percentage of empty stomachs among age groups, between sexes, and between eastern and western parts of Latvia. Interpretation and implications to wolf conservation policy based on the given results are suggested.

In Latvia, livestock depredation by wolves has increased during the last two decades. Most of the attacks occur in summer and autumn during wolf hunting season. Use of effective preventive measures in Latvia is low, and farmers primarily rely on wolf hunting as a depredation reduction measure. The total numbers of wolf attacks and number of affected sheep per year in regional forest management units were analyzed in relation to the estimated wolf density, extent of culling, and proportion of juveniles, as well as the sheep density and estimated number of wild prey animals. The response variables (number of attacks and affected sheep per year) were modelled using a negative binomial regression, testing the effects of every covariate separately and building models from the significant covariates. The depredation level was related to sheep density and estimated wolf population size. No reducing effect was found for culling, and an even greater depredation rate was expected when the proportion of culled wolves increased. In addition, no significant effect was associated with the other covariates. However, greater numbers of affected sheep were expected at higher red deer density, suggesting increased opportunistic livestock depredation when red deer locally outcompete roe deer, the preferred wolf prey in Latvia.

Large carnivores are essential components of natural ecosystems. In populated areas, their conservation depends on preserving a favorable status in coexistence with humans, which may require the elimination of excess carnivores to minimize public concerns. As the Baltic region currently hosts a thriving wolf population, locally sustainable management of wolves is important for preserving biodiversity at a European scale. In this paper, we provide a dynamic assessment of the Latvian wolf subpopulation from 1998 until 2020. This study is based on age composition and fecundity data from teeth, uteri, and ovaria inspections obtained from samples of legally culled or accidentally killed individuals. The abundance estimates indicated population growth that exceeded the previously predicted carrying capacity. The proportion of juveniles among the culled individuals increased in recent years, but the mean age of culled adults exhibited a stable trend. In presumably nonselective hunting, the juveniles and individuals older than 3 years had greater culling mortality estimates in comparison with other age classes, and the culling rates for adult females of particular age classes were higher than for males of the same age. While creating significant hunting pressure, wolf management in Latvia may have contributed to the population growth by affecting its demographic processes.

The acceptance of large carnivores is one of the key issues for their conservation. We analyzed the level acceptance of brown bears (Ursus arctos Linnaeus, 1758) amongst 10–18 year old school students in four European countries using anonymous questionnaires. Our aim was to characterize the drivers of species acceptance, described as a rural–urban cline, as well as fear levels and the respondents’ familiarity with bears. We found lower levels of acceptance of bears were related to fear of bears and that bear acceptance was not higher in the bear-inhabited countries, but urban inhabitants tended to better accept the species. Factor analysis revealed the importance of country-related aspects, familiarity with bears, experiences in human-wildlife conflict, gender-age differences, respondent’s relationship to nature and the origin of their knowledge of the species. We consider that bear-related education and mass media in Latvia and Lithuania could reduce fear of these animals and sustain their acceptance, while human–wildlife conflict management measures in Bulgaria and Turkey are recommended to boost the appreciation of the species.

A survey was carried out to determine the attitudes of the general public and of hunters towards wolves (Canis lupus) in Latvia. Today wildlife conservation depends on effective management practices; however, these are often influenced by public opinions and attitudes. Our aim was to understand the causes behind these attitudes and to compare our results with previous research done in Latvia. Questionnaires were distributed through schools and hunter organisations. The attitudes of both the general public and hunters were mostly neutral or positive. Older people and women were generally less positive. Respondents with less positive attitudes were more likely to say that wolf numbers in the country should be decreased. Significant associations between attitudes, beliefs of wolves causing damage and financial losses and what should be done with wolf numbers in Latvia were found. Three attitude predictors were established.

Nowadays, genetic research methods play an important role in animal population studies. Since 2009, genetic material from Latvian wolf specimens obtained through hunting has been systematically gathered. This study, spanning until 2021, scrutinizes the consequences of regulated wolf hunting on population genetic metrics, kinship dynamics, and social organization. We employed 16 autosomal microsatellites to investigate relationships between full siblings and parent–offspring pairs. Our analysis encompassed expected and observed heterozygosity, inbreeding coefficients, allelic diversity, genetic distance and differentiation, mean pairwise relatedness, and the number of migrants per generation. The Latvian wolf population demonstrated robust genetic diversity with minimal inbreeding, maintaining stable allelic diversity and high heterozygosity over time and it is not fragmented. Our findings reveal the persistence of conventional wolf pack structures and enduring kinship groups. However, the study also underscores the adverse effects of intensified hunting pressure, leading to breeder loss, pack disruption, territorial displacement, and the premature dispersal of juvenile wolves.
